Compare load ratings quoted in kN, kgf or lbf on cables, anchors, springs and fasteners.
Solve F = m·a problems in newtons, or convert CGS dynes to SI.
Convert push, pull or clamping forces in datasheets to a unit you can compare.
A kilogram is a unit of mass; a kilogram-force is the force gravity exerts on 1 kg at standard gravity: 9.80665 N. Do not confuse the two.
1 lbf is about 4.45 N, and 1 kN is about 225 lbf.
One kilogram-force equals exactly 9.80665 newtons (standard gravity).
Multiply lbf by 4.4482216. For example, 100 lbf ≈ 444.82 N.
A dyne is the CGS unit of force: 1 dyne = 10⁻⁵ newton, the force that accelerates 1 gram at 1 cm/s².
A newton is roughly the weight of a small apple (about 102 grams) on Earth.
